Thats actually not true. My Hellen had yellow on her back legs and she was most definitely female. Its just part of the coloring for the species. Its possible that it gets brighter when another male is around (but it would make more sense that it would get brighter when a female is around. kinda like a male bird plumping up its colorful feathers to impress a possible mate) but I'm not sure. But all Grays have the yellow on the inner parts of the back legs.

Grays are easy to tell if there male or female. White throat is girl, dark brown or black is male. This wont change even when they change to match there surroundings. They are very chameleon like. Hell displayed all kinds of colors from almost pure white to a green very similar to my store bought green tree frog (yup. even though there "gray" they can still turn green to blend in) to almost black and every color in between. Females make noises similar to croaking but not as often as males do. Hellen sometimes made this chirping noise around dinner time or when the cat was being too friendly with the tank. Azy (my whites female) made this little call a few times since I've had her but nothing constant.

Now constant calling could either be a male or a female who desires constant attention (they are a communal frog by nature). Now some may disagree with me but Hell always loved it when I took her out of her tank and handled her. She would sit on my upper chest and watch tv with me or on my shoulder ect ect. They are a very hardy frog and do stand up to handling pretty well. So if you have a white throat you do have a girl but if shes making lots of noise you may look into getting her a tank mate (I got Percy, a captive bred green and they were actually very happy together. you could also look around and see if you can find another gray) or lavish her with attention yourself. :3
